Expand description

A struct holding the current voting state of the blockchain.

Implementations§

Source§

impl HFVotes

Source

pub fn new(window_size: usize) -> Self

Source

pub fn add_vote_for_hf(&mut self, hf: &HardFork)

Add a vote for a hard-fork, this function removes votes outside of the window.

Source

pub fn reverse_blocks(&mut self, numb_blocks: usize, old_block_votes: Self)

Pop a number of blocks from the top of the cache and push some values into the front of the cache, i.e. the oldest blocks.

old_block_votes should contain the HFs below the window that now will be in the window after popping blocks from the top.

§Panics

This will panic if old_block_votes contains more HFs than numb_blocks.

Source

pub fn votes_for_hf(&self, hf: &HardFork) -> usize

Returns the total votes for a hard-fork.

ref: https://monero-book.cuprate.org/consensus_rules/hardforks.html#accepting-a-fork

Source

pub fn total_votes(&self) -> usize

Returns the total amount of votes being tracked

Source

pub fn current_fork( &self, current_hf: &HardFork, current_height: usize, window: usize, hfs_info: &HFsInfo, ) -> HardFork

Checks if a future hard fork should be activated, returning the next hard-fork that should be activated.
